本研究主旨在設計高產氫效率的流動型產氫觸媒反應流床，以氧化鈷為催化劑水解硼氫化鈉產生氫氣與過硼酸鈉。利用單因子實驗法找出影響產氫觸媒流床設計之參數，進而藉由實驗分析比較，設計高化學轉換效率及穩定氫氣生成之創新產氫觸媒流床。本創新產氫觸媒流床以具有氣道之流道概念可有效分離水溶液及氫氣，迅速導出所需氫氣，增加硼氫化鈉與催化劑接觸機會；本流床的另一特點以流道上游具有液氣不互擾之流道空間，可使提供反應之硼氫化鈉不受氫氣生成影響，增加氫氣生成之穩定性，藉由以上特點，將可大幅提高產氫效率及抑制不穩定之氫氣生成率。
實驗中探討傳統流動型產氫觸媒流床之產氫特性，以此為依據設計創新產氫觸媒流床，探討創新流床之體積流率、催化劑擺放位置、流床面積比、流床寬度比、流床大小及流床角度對化學轉換效率與氫氣生成振幅之影響，並以多相流流場及傅立葉轉換比較傳統流床及創新流床之特點。本文成功利用流場改質並驗證具有氣道及液氣不互擾空間，將有助於化學轉換效率及氫氣生成之穩定性，本創新產氫觸媒流床可應用於各類型氫能工具機前端，適用於多相流產氫，可舒緩能源短缺及環境保護之問題。

This study emphasizes on developing a novel reactor for hydrogen generation. Oxide cobalt is used as catalyst to hydrolyze sodium borohydride. In order to find the factors which influence chemical efficiency and hydrogen generation amplitude, one-factor-at-a-time method is used in the experiment. This novel reactor can separate liquid and hydrogen based on the concept of air flow channel; therefore, hydrogen can be quickly removed from catalyst surface. The chance of contact between sodium borohydride and oxide cobalt can be increased, and the efficiency of chemical reaction can also be improved. Another characteristic of this novel reactor is the steady rate of hydrogen generation. Because of the upstream space of flow channel, sodium borohydride is not influenced by hydrogen generation. Thus sodium borohydride can be continuously supplied to catalyze the generation of hydrogen. According to these two characteristics, this novel reactor can improve chemical efficiency and decrease hydrogen generation amplitude.
This research first discusses characteristics of a conventional reactor by experiments, and then to design a novel reactor based on the results. The effects of volumetric flow rate, catalyst position, the area and width ratio of the reactor, and also the size and angle of the reactor on chemical conversion of this novel reactor have been systematically investigated. Finally, by using multiphase flow field and the Fourier Transform, the results can be compared between the conventional reactor and the novel one. In this study, it is proved that a reactor which has air flow channel and upstream space can improve chemical efficiency and decrease hydrogen generation amplitude. This novel reactor can be applied to facilities that needed hydrogen as a power source, and it is suitable for multiphase hydrogen generation. It can reduce the problem of energy shortage and achieve environmental friendliness.
